The theory hinged on the creation of matter between galaxies over time, so that even though galaxies get further apart, new ones that develop between them fill the space they leave. The resulting universe is in a "steady state" in the same manner that a flowing river is—the individual water molecules are moving away but the overall river ...
2001: A Space Odyssey is a 1968 epic science fiction film produced and directed by Stanley Kubrick.The screenplay was written by Kubrick and Arthur C. Clarke.Its plot was inspired by several short stories optioned from Clarke, primarily "The Sentinel" (1951) and "Encounter in the Dawn" (1953). [3]
Observations made by Edwin Hubble during the 1930s–1950s found that galaxies appeared to be moving away from each other, leading to the currently accepted Big Bang theory. This suggests that the universe began very dense about 13.787 billion years ago, and it has expanded and (on average) become less dense ever since. [1]
At the time of the movie's making, the space race was in full swing, and the use of space and technology for war and destruction was seen as a great challenge of the future. [ 37 ] But the use of tools also allowed mankind to survive and flourish over the next four million years, at which point the monolith makes its second appearance, this ...
The Big Crunch is a hypothetical scenario for the ultimate fate of the universe, in which the expansion of the universe eventually reverses and the universe recollapses, ultimately causing the cosmic scale factor to reach absolute zero, an event potentially followed by a reformation of the universe starting with another Big Bang.
Some large black holes in the universe are predicted to continue to grow up to perhaps 10 14 M ☉ during the collapse of superclusters of galaxies. Even these would evaporate over a timescale of up to 10 106 years. [17] After that time, the universe enters the so-called Dark Era and is expected to consist chiefly of a dilute gas of photons and ...
If the universe is homogeneous at a large scale, then there would be four times as many stars in a second shell between 2,000,000,000 and 2,000,000,001 light years away. However, the second shell is twice as far away, so each star in it would appear one quarter as bright as the stars in the first shell.
The expansion of the universe is the increase in distance between gravitationally unbound parts of the observable universe with time. [1] It is an intrinsic expansion, so it does not mean that the universe expands "into" anything or that space exists "outside" it.
